30mg is not really that crazy, but is definitely on the upper end of what should be used.
That being said I think 1 pill a day for most is going to a be a very nice surprise cycle. Good strength, lean mass and some recomp from 3,4-estra. I think "Tren" gets run a little too high in some cases, especially stacked. I think things can be run a little lower when stacked together as the compliment each other and produce a synergism.
Ratios may be a tad off I will agree, but it is a potent pill and has some great feedback so Purus hasn't felt the need to change it. It is legit stuff for sure.
